MMBD701LT3G

RF Diode Overview

The MMBD701LT3G is a Schottky barrier rectifier manufactured by onsemi, housed in a surface-mount SOT-23 package with three terminals. It features a peak repetitive reverse voltage (Vrrm) of 70 V and a maximum continuous forward current (If) of 10 mA. The device exhibits a low forward voltage drop (Vf) of 1 V at the rated current and a low peak reverse leakage current (Ir) of 200 nA. Designed for high-speed switching applications, it operates within a temperature range from -55°C to +125°C. The component complies with RoHS standards and is lead-free.

RF Diode Feature Summary

• Schottky barrier technology enables fast switching speeds and minimal power loss during conduction.
• Low forward voltage drop reduces overall system power consumption and heat generation.
• Compact SOT-23 surface-mount package facilitates automated assembly and space-constrained designs.

RF Diode Applications

• High-frequency rectification in low-power DC-DC converters
• Protection against reverse polarity in battery-powered devices
• Clamping diodes in logic circuits and signal processing paths

RF Diode Procurement Notes

Verify the specific ordering suffix to confirm the reel quantity and tape-and-reel specifications required for your manufacturing line. Ensure that the procurement channel provides traceability documentation consistent with onsemi's quality management systems. Cross-reference the part number with official distributor catalogs to confirm availability status and compliance certifications such as RoHS and Pb-Free declarations before finalizing orders.

RF Diode Selection Notes

Select this component when a low-capacitance, fast-recovery Schottky diode is needed for signals or currents up to 10 mA. The 70 V reverse voltage rating provides adequate margin for most low-voltage logic and power rails. Consider the thermal resistance and package size if multiple devices are placed closely together on the PCB to ensure junction temperatures remain within the specified operating range under all expected load conditions.

RF Diode Part Context

This part belongs to onsemi's MMBD series of small-signal Schottky diodes, which are widely used in consumer electronics and industrial control systems. The SOT-23 form factor is standard for compact portable devices. The LT1G suffix typically denotes a specific taping and reel configuration for automated placement equipment, distinguishing it from cut-tape or bulk packaging variants.

RF Diode Replacement Considerations

Direct replacements must match the 70 V Vrrm, 10 mA If, and SOT-23-3 package dimensions. Verify that substitute Schottky diodes offer comparable forward voltage and reverse leakage characteristics to maintain circuit efficiency. Check pinout compatibility to ensure anode-cathode orientation aligns with the original design layout without requiring PCB modifications.
